"The day my son was due to be born, I got a phone call from my mum," the mum-of-two continues her heart-wrenching reveal.
"He had a motorbike accident that day. He died."
"Having a child is meant to be the best day of your life; so I’m going through these mixed emotions where I’ve got this beautiful blessing coming but I’ve just lost my best friend and basically my father figure. I was overwhelmed with everything that was going on."
Stacey – whose little boys are now two and four years old – recognises the impact this had on her, and how it's shaped her relationships since.
"I ended up stepping up for the family and I handled everything," she explains of how she dealt with the aftermath of her brother's tragic passing.
"I had to push all my emotions aside. I think that is the reason I do have walls and I am standoffish and I don’t trust people very often. I don’t want to get hurt."
"I’ll push people away because I don’t want to open up that side of me."
After deciding to be a part of the this year's version of Australia's favourite televised social experiment, Stacey's now hoping the experts can find her someone to help "bring her walls down and help her show affection".
"I want to be emotional towards someone and have them do the same back," she tells one of the show's relationship experts, John Aitken, as she fights back tears.
"Because I have love to give as well. I have a lot of love to give."
Stacey has already incurred the wrath of former MAFS babe Jessika Power, who took to Instagram to slam the beautiful blonde.
"What I see here is a girl who's 25 [sic], gone on this show and just gaslighted the s--t out of [fellow participant Hayley Vernon], who has actually worked her entire ass off to be fit, healthy and brought herself out of the darkest of places," Jessika shared on her Instagram story, with two photos of Stacey.
"All to be labelled and slandered by someone who is clearly insecure that someone may bag more 'air time' than her," the controversial season six alum continued.
"[Stacey] even wrote to me that she thought she was the new 'me' on the show."
